TJ Shehee of Mead, who qualified for the 2017 U.S. Junior Amateur, and Katie Berrian of Castle Rock grabbed the lead in their respective divisions after Monday's first round of the Colorado Junior Amateur at Todd Creek Golf Club in Thornton.
Shehee fired a 6-under-par 66 to grab a three-stroke advantage among the boys. And Berrian posted an even-par 72 to go up by three in the girls tournament.
